Cullen explains that the idea behind the food forest is to grow a mix of food-producing species, layered in the same way that a forest is. There’s a herbaceous layer at ground level, a shrub layer, and a canopy layer of trees above. With time, the food forest becomes self-maintaining and, with the appropriate mix of plant species, can have self-renewing fertility. The top layer of the food-forest garden is the “canopy” layer. Cullen says that they planted this layer with fruiting tree species including cherries, plums, persimmon—and even a hawthorn.The lower herbaceous and shrub layers, which are still being developed, will be a polyculture—a mix of different plants. Along with edible properties, plants in the lower layers might make available soil nutrients (deep-rooted plants bring up nutrients,) supply nutrients (pea shrubs capture nitrogen from the air,) and attract pollinator species.Lower-layer plants include bee balm, chamomile, rosa rugosa (for rose hips), strawberreis, and blueberries. Cullen says that this list will grow, as there is still a lot of planting to do in this layer.
